Unlike in most presentation applications, a Sozi document is not organised as a slideshow, but rather as a poster where the content of your presentation can be freely laid out. Playing such a presentation consists in a series of translations, zooms and rotations that allow to focus on the elements you want to show.

Sozi is based on open standards. It is free software distributed according to the terms of the GPL 3.0.

I think inkscape is going to be a bit big and heavy on the N900 if it really needs inkscape installed, but the others ought to be do-able (dont know how easy). Presume you would plan on showing this via the TV out, not directly on device. Can the app output presentations to web pages with the dynamic stuff done in javascript? Or try something else that does something more supported?

It seems, that presentations produced by sozi are simple .svg (scalable vector graphic) files, with set frames. Cool! It means, that they can be played without problems via microB, as AaapoRantalainen said.

So, whole thing about running Sozi in N900 is centered around its (Sozi) ease of usage, for creating animated svg's? Maybe there are more FOSS, lightweight alternatives to that, not requiring inkscape?

Also, as GIMP is working fine through Easy Debian, no reasons, why Inkscape shouldn't. Sozi is just an extension to the latter.

Ok...
Installed Sozi in easy-debian First inskape and had to download Sozi-deb and installed through Debian-Chroot (it wasn't in repos?)

tried a little it last a litle bit to start (inskape) but then it's preaty usable I think. Dind't tried Sozi extention yet as soon as I can nd learn a litle about the use I'll give my impression.
Thanks
